ReverseEdgeDuplicator<I extends org.apache.hadoop.io.WritableComparable,E extends org.apache.hadoop.io.Writable>	An EdgeReader that creates the opposite direction edge for each edge read.
VertexInputFormat<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable>	Use this to load data for a BSP application.
VertexOutputFormat<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable>	Implement to output the graph after the computation.
VertexReader<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable>	Analogous to Hadoop's RecordReader for vertices.
VertexValueInputFormat<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable>	Vertex input format that only allows setting vertex id and value.
VertexValueReader<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable>	Vertex reader for VertexValueInputFormat.
VertexWriter<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable>	Implement to output a vertex range of the graph after the computation
